Instance Method Details
#create_generated_attribute(attribute_type, name = "test", index = nil)
Create a ::Rails::Generators::GeneratedAttribute
by supplying the attribute type and, optionally, the attribute name:
create_generated_attribute(:string, "name")
# File 'railties/lib/rails/generators/testing/behavior.rb', line 85
def create_generated_attribute(attribute_type, name = "test", index = nil) Rails::Generators::GeneratedAttribute.parse([name, attribute_type, index].compact.join(":")) end
#generator(args = default_arguments, options = {}, config = {})
Instantiate the generator.
# File 'railties/lib/rails/generators/testing/behavior.rb', line 77
def generator(args = default_arguments, = {}, config = {}) @generator ||= generator_class.new(args, , config.reverse_merge(destination_root: destination_root)) end
#prepare_destination (private)
Clears all files and directories in destination.
# File 'railties/lib/rails/generators/testing/behavior.rb', line 99
def prepare_destination # :doc: rm_rf(destination_root) mkdir_p(destination_root) end
#run_generator(args = default_arguments, config = {})
Runs the generator configured for this class. The first argument is an array like command line arguments:
class AppGeneratorTest < Rails::Generators::TestCase
tests AppGenerator
destination File. ("../tmp", __dir__)
setup :prepare_destination
test "database.yml is not created when skipping Active Record" do
run_generator %w(myapp --skip-active-record)
assert_no_file "config/database.yml"
end
end
You can provide a configuration hash as second argument. This method returns the output printed by the generator.
# File 'railties/lib/rails/generators/testing/behavior.rb', line 67
